Unique contributions to the Fusion Roadmap (max. 5 slides) unique contributions of DTT to Mission 1: Plasma regimes of operation and to Mission 6: Integrated DEMO design and system development
10-year perspective
(main limitation low power (max 20 MW), but high current (up to 4 MA) high field should be accessible in time for 10 years plan
Development of reactor relevant ELM-free and small ELM regimes and corresponding scenarios to enable longer term perspective
Produce corresponding low and high Ip and BT plasmas in the same device to better determine L-mode and H-mode confinement dependencies on current and field
Physics of edge / pedestal transport in neutral opaque conditions with strong electron heating and different levels of impurity seeding
Study transport in plasmas with high electron heating and low torque and strategies of improving ion energy confinement in plasmas with Te/Ti>1
Longer term perspective
Determination of a fusion reactor high confinement regime, possibility of studying ELM-free and small ELM regimes at reactor separatrix densities concomitantly with reactor pedestal top collisionalities, with W wall at reactor P(B)/R and neutral opaque edge
Reactor exhaust demonstration : lambda_q vs current , at power … (point to be determined with EG 2)
Qualify reactor type of scenarios with high radiating fractions and impurity behaviour at reactor parameters, for unprecendented core-edge integration physics. Full field / full current for reactor relevant edge – SOL, half field / half current for reactor relevant normalized pressure (beta)
Determine confinement dependence on current and field, including possibility of exploring on the same device high BT, low fGRW and low BT high fGRW
Integrated reactor relevant confinement regime with energetic particles fulfilling expected burning plasma dimensionless characteristic parameters
Perform study of transport in plasmas with high electron heating and low torque and determine strategies of improving ion energy confinement in plasmas with Te/Ti>1 (at higher power and higher current) Template for input to facilities review<br>

Important contributions to the Fusion Roadmap (max. 5 slides) important contributions of DTT to Mission 1: Plasma regimes of operation and to Mission 6: Integrated DEMO design and system development
10-year perspective
Parametric dependencies of H-mode threshold in impurity seeded plasmas and various divertor configurations
Effects of high shaping on edge transport
Negative triangularity scenarios and extrapolability to a reactor
Transport properties with negligible core particle source at high power
Longer term perspective
I- mode scenarios, domain of existence and confinement properties from low to high field in the same device
High-b scenarios in full W wall device at concomitant reactor collisionality and density Template for input to facilities review<br>
